Benefits of technology
The present invention relates to an endoscope with a treatment instrument riser, a driving mechanism, a guide-wire securing unit, a guide-wire securing operation member, and a securing unit for securing the position of the guide-wire securing operation member. The invention also includes a tube-like member for inserting a treatment instrument and a channel for inserting the treatment instrument. The technical effects of the invention include improved guidance and positioning of treatment instruments, simplified operation, and improved maneuverability of the endoscope.
Problems solved by technology
Since the pancreatic duct, bile duct, hepatic duct, and the like are extremely thin ducts, the insertion of the distal-end portion of the insertion portion of the endoscope into these ducts at the endoscopic treatment of the pancreatic duct, bile duct, hepatic duct, and the like is difficult to perform.
Since the pancreatic duct, bile duct, or hepatic duct is an extremely thin duct, as described above, the insertion of the guide wire thereinto is difficult to perform.
Therefore, it is extremely cumbersome and troublesome for the operator to reinsert the guide wire into the pancreatic duct, bile duct, hepatic duct or the like many times.
Such an operation is extremely cumbersome for the operator and the assistant.
As a result, the endoscopic diagnosis and treatment require high personnel cost, thereby placing a high financial burden on both the hospital and the patient.

Embodiment Construction
[0031] Exemplary embodiments of an endoscope according to the present invention will be described below with reference to the accompanying drawings. It should be noted that the present invention is not limited to the embodiments.
[0032]FIG. 1 is a perspective view of an endoscopic apparatus including an endoscope according to a first embodiment of the present invention and a peripheral device thereof seen from above from the right-hand side, and FIG. 2 is a partially enlarged perspective view of a distal-end portion of the endoscope of FIG. 1.
[0033] As shown inFIG. 1, an endoscopic apparatus 100 includes an endoscope 1 and a peripheral device 50. The endoscope 1 mainly includes an operation portion 13, an insertion portion 12, and a universal chord 14. An insertion portion protecting member 33 is arranged to protect the insertion portion 12 at a position where the insertion portion 12 and the operation portion 13 are connected.
[0034] The peripheral device 50 mainly includes variou...

An endoscope according includes a treatment instrument riser which guides a distal end of a treatment instrument projected from a distal end opening provided in a channel for inserting the treatment instrument in an insertion portion to a desired position; a driving mechanism which is rotatably fitted onto an axis provided in an operation portion covered with an outer packaging member, and drives the treatment instrument riser; a guide-wire securing unit which secures a position of a guide wire projected from the distal end opening provided in the channel in the insertion portion; a guide-wire securing operation member which operates the guide-wire securing unit; and a securing unit which secures a position of the guide-wire securing operation member in a state where the position of the guide-wire is secured.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of PCT international application Ser. No. PCT / JP2005 / 012341 filed Jul. 4, 2005 which designates the United States, incorporated herein by reference, and which claims the benefit of priority from Japanese Patent Application No. 2004-197309, filed Jul. 2, 2004, incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to an endoscope which is employed for treatment of an affected area and in which a guide wire is made to project from a distal-end opening provided in a treatment instrument insertion channel of an insertion portion and used as a guide to guide a treatment instrument to the affected area. [0004] 2. Description of the Related Art [0005] According to conventionally known techniques, an operator carries out various treatments in body cavities by inserting an endoscope into the body cavities, selectively inserting various ...
